Traumatic arteriovenous fistula 52 years after injury

Computed tomography angiogram demonstrating equal contrast opacification in both the dilated external iliac artery (short arrow) and dilated external iliac vein (long arrow) in a patient with a right groin AVF.

Angiography performed via a left groin puncture demonstrating the dilated right ileo-femoral arteries (short arrow) and arterio-venous communication at the level of the deep femoral artery (long arrow).

A, Mid-procedure angiography demonstrating proximal deep femoral arterial branches (arrow) filling the AVF and adjacent vein via collateral branches. B, Completion angiography following embolization of the AVF with maintained flow via the deep femoral artery branches and absence of flow in the adjacent veins.

Follow-up computed tomography angiogram demonstrating lack of contrast in, and normalization in diameter of, right external iliac vein (long arrow). Note persistent dilation of the right external iliac artery (short arrow) in comparison to normal contralateral external iliac artery (arrowhead).
